    Genetic variation, environment and demography intersect to shape Arabidopsis defense metabolite variation across Europe

    Ella Katz et al.
    Measurements of specialized metabolites across a population of 800 natural Arabidopsis thaliana accessions revealed different pressures and evolutionary processes that shaped their variation and distribution across Europe.

    Plant Ecology: Getting the metabolites right

    Arthur Korte
    A study of almost 800 Arabidopsis thaliana plants from across Europe reveals how the environment and evolutionary pressures shape their metabolites.

    A gustatory receptor tuned to the steroid plant hormone brassinolide in Plutella xylostella (Lepidoptera: Plutellidae)

    Ke Yang et al.
    The gustatory receptor PxylGr34 is tuned to the steroid plant hormone brassinolide and mediates the deterrent effects of brassinolide on feeding and ovipositing behaviors in Plutella xylostella.

    Expansion of the circadian transcriptome in Brassica rapa and genome-wide diversification of paralog expression patterns

    Kathleen Greenham et al.
    Whole genome duplication in Brassica rapa is accompanied by both expansion of the circadian transcriptome and widespread temporal reconfiguration of gene regulatory networks consistent with subfunctionalization among pairs of paralogs.

    Parallel global profiling of plant TOR dynamics reveals a conserved role for LARP1 in translation

    M Regina Scarpin et al.
    Plants and humans use a shared mechanism, the eukaryotic metabolic sensor TARGET OF RAPAMYCIN protein kinase and its substrate, an RNA-binding protein called LARP1, to coordinate post-transcriptional gene expression.

    Oomycete small RNAs bind to the plant RNA-induced silencing complex for virulence

    Florian Dunker et al.
    Small RNAs of distantly related plant pathogens, such as fungi and oomycetes, hijack the plant RNA-induced silencing complex to favor host infection.

    Independent evolution of ancestral and novel defenses in a genus of toxic plants (Erysimum, Brassicaceae)

    Tobias Züst et al.
    A gain-of-function in a new chemical defense resulted in no trade-offs and and independent evolution between novel and ancestral defenses, suggesting low redundancy among different defensive chemicals.

    Homeostasis of branched-chain amino acids is critical for the activity of TOR signaling in Arabidopsis

    Pengfei Cao et al.
    Despite BCAAs being de novo-synthesized in chloroplasts, TOR activation by BCAAs is conserved in plants and triggers a re-organization of actin and actin-associated endomembranes.

    Tritrophic metabolism of plant chemical defenses and its effects on herbivore and predator performance

    Ruo Sun et al.
    Genetic manipulation demonstrates the costs and benefits of detoxifying glucosinolate plant defenses in a pest insect and its predator.
